在二维和三维空间中以图形方式描绘物体的能力是工程设计实践的基础。从历史上看，工程师们使用铅笔、纸和橡皮来起草初步草图，并将初步草图转化为精确的生产图纸。随着计算机辅助设计（CAD）软件程序的普及，描述几何和手工绘图的教学在很大程度上已经从工程教育课程中消失了。本文描述了描述几何和手工绘图教学的历史。本文还提出了一个案例研究，探讨了在工程设计图形课上，有和没有补充几何和绘图教学的CAD教学对学生空间能力发展的贡献。
The ability to graphically depict objects in two- and three-dimensional space is fundamental to engineering design practice. Historically, engineers have used pencil, paper, and erasers to draft preliminary sketches and to transform initial drafts into precise production drawings. With the proliferation of computer- aided design (CAD) software programs, instruction in descriptive geometry, and manual drawing has largely vanished from engineering education programs. This article describes the history of instruction in descriptive geometry and manual drawing. It also presents a case study that investigates the contribution of CAD instruction with and without supplemental instruction in descriptive geometry and drawing to the development of students’ spatial abilities in an engineering design graphics class.
